The focus of this second workshop is on definition practices in either human or machine-assisted ontology development.</div><div style="font-family: Arial;"><br></div><div style="font-family: Arial;">PRESENTATION</div><div style="font-family: Arial;">A current problem in ontology development is constructing the needed definitions of terms either logical or in natural language. For example, ontologies built using OBO Foundry principles are advised to include both logical and natural language definitions, but ontology developers too often focus on only one of these, or they pay insufficient attention to whether they are equivalent.</div><div style="font-family: Arial;"><br></div><div style="font-family: Arial;">Explicit definitions of terms in ontologies serve a number of purposes. Logical definitions allow reasoners to create inferred hierarchies, lessening the burden of asserting and checking the validity of subsumptions. Natural language definitions help to ameliorate the pervasive problem of low inter-annotator agreement. In specialized domains, experts will know their own field well, but may only have limited knowledge of adjacent disciplines. Good definitions make it possible for non-experts to understand unfamiliar terms and thereby make it possible for more confident reuse of terms by external ontologies, which in turn facilitates data integration.</div><div style="font-family: Arial;"><br></div><div style="font-family: Arial;">The goal of this workshop is to bring together interested researchers and developers to explore these issues by presenting case studies in a biomedical domain discussing the difficulties that arise when constructing definitions with a view to sharing strategies in the future. Even in the seemingly narrow domain of definition construction, cross-fertilization from related disciplines should yield benefits in quality and help to identify novel approaches.</div><div style="font-family: Arial;"><br></div><div style="font-family: Arial;">Papers submitted should include one or more case studies and raise specific questions related to definitions with a link to a biomedical domain. Reports on successful or unsuccessful methods are both appropriate.</div><div style="font-family: Arial;"><br></div><div style="font-family: Arial;">TOPICS</div><div style="font-family: Arial;">-experiences in formulating definitions</div><div style="font-family: Arial;">-tools that assist in definition editing, including collaborative systems</div><div style="font-family: Arial;">-coordination of logical and textual definitions</div><div style="font-family: Arial;">-validation and quality control of definitions, e.g., checking that definitions comply with the all/some form</div><div style="font-family: Arial;">-methods for constructing definitions from multiple sources</div><div style="font-family: Arial;">-use of controlled languages such as Rabbit or ACE for more user-friendly logical definition creation</div><div style="font-family: Arial;">-use of templates to systematize definition creation</div><div style="font-family: Arial;"><br></div><div style="font-family: Arial;">FORMAT AND OUTCOMES</div><div style="font-family: Arial;">This will be a half-day workshop with a selected mix of presentations based on accepted papers. In order to promote discussion, each presentation will be followed by a short response by a participant of the workshop to be arranged in advance of the workshop.</div><div style="font-family: Arial;"><br></div><div style="font-family: Arial;">This workshop will document findings on the workshop’s website (<a href="https://sites.google.com/site/definitionsinontologies/">https://sites.google.com/site/definitionsinontologies/</a>).
